‘You’re always right with wine’: Meet the woman behind 1 in every 4 bottles of Oregon wine sold in America.

Amy Prosenjak was running inventory for a billion-dollar furniture company in Ohio when her husband floated an idea that would change their lives.

Prosenjak and her husband were in their early 30s and had fallen in love with wine tourism, traveling to Napa and to Italy whenever they had the chance.

One day, her husband asked why she didn’t get a job in the wine business.

“I said, ‘Well, who would hire me?'” Prosenjak recalled.

“And he said, ‘I don’t know.'” WineJobs.com answered that question for them.

A to Z Wineworks, then a small Oregon winery owned by two couples and in the process of buying Rex Hill, happened to be looking for a chief financial officer, and Prosenjak said she sent her resume “kind of on a whim.” One of A to Z’s founders, Bill Hatcher, who was CEO at the time, called to ask whether she understood cost accounting, and Prosenjak replied, “I’m the director of inventory for a $1 billion furniture company.

That is my specialty.” “He said, ‘Well, I can teach you the wine business,'” Prosenjak said.

“And he did.” Prosenjak sold her house, moved across the country and began what she calls a “wonderful and wild 20-year ride.” Today, 53-year-old Prosenjak is president and CEO of A to Z Wineworks LLC, overseeing A to Z, Erath and Rex Hill, brands that account for roughly one in every four bottles of Oregon-origin wine sold in U.S. multi-outlet retail, according to Circana data.

That measure covers grocery, mass, club and drugstores, but leaves out restaurants, tasting rooms and most independent wine shops.

The industry Prosenjak learned to scale has changed drastically.

After years of expansion, production across the company’s brands fell about 32% in 2025 to 550,000 9-liter cases, according to the company.

A to Z expects to remain around that level in 2026.

“We’re going to follow the consumer,” Prosenjak said.

“If we need to be a slightly smaller company, we will do that because we’re going to stay true to our winemaking values.
